The C-30ZX Ozone Monitor is a compact, fixed-mount ozone detector designed for continuous ozone safety monitoring in accordance with OSHA standards. With a detection range of 0.02 to 0.14 ppm, integrated audible alarm, relay control, and analog output, the C-30ZX is a simple yet powerful tool for facilities that need dependable ozone detection and control.
Key Features of the C-30ZX Ozone Monitor
- Detection Range: Measures ozone levels from 0.02 to 0.14 ppm in 0.02 ppm increments
- Visual Display: Multicolor LED bargraph display that transitions from green (safe) to yellow (caution at 0.05 ppm) and red (danger at 0.10 ppm)
- Audible Alarm: Alerts users when ozone levels exceed the set threshold; can be disabled with a front-facing switch
- Relay Control: Built-in relay activates simultaneously with the alarm to control equipment or trigger additional safety systems
- Analog Output: 0–2 VDC output for integration with external systems such as PLCs, data loggers, or wireless monitoring kits
- Response Time: Extremely fast—detects ozone presence in tenths of a second
- Maintenance: Minimal upkeep; annual calibration recommended; sensor life is approximately two years
Benefits
- Real-Time Monitoring: Continuously tracks ozone levels and provides instant feedback with visual and audible alerts
- Plug-and-Play: Simple setup with no installation required for most applications
- Compact and Lightweight: Small form factor (3.25″ x 1.375″ x 2.375″, 5 oz) for easy wall mounting in any facility
- User-Adjustable Alarm Setpoints: Customize your alarm and relay triggers from 0.02 to 0.14 ppm using internal DIP switches
- Integrated Control: Use the relay output to shut down ozone generators, activate fans, or trigger safety interlocks
Technical Specifications
- Measurement Method: Heated Metal Oxide Semiconductor (HMOS)
- Display Type: LED bargraph – green (normal), yellow (caution), red (danger)
- Analog Output: 0–3 V for data loggers and monitoring systems
- Power Requirement: 12 VDC at 300 mA; AC adapters available
- Alarm and Relay Trigger: Default at 0.1 ppm; programmable in 0.02 ppm increments

- Calibration: Annual recommended; includes calibration certificate
- Sensor Life: ~2 years (replacement required after failure)
C-30ZX as a Relay Controller
The internal relay of the C-30ZX can be configured to activate external systems when ozone reaches the user-defined threshold. This allows automation of ventilation systems, ozone generator shut-off, or activation of visual alarms. DIP switches and terminal connections are easily accessible on the rear of the unit for setup.
